Help with drawing strings on JFrame?!?!
Hey guys, I'm really new to Java (just started AP Comp Sci last month), and we had a project to build a Mastermind application using numbers, which I did. However, I'm trying to learn more on my own, and was hoping to use the example code my teacher gave me to output what I want to say to a JFrame instead of just the command prompt.
Here is the code for my Mastermind class:
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Mastermind extends JFrame
public static void main(String args[])
int master[] = new int[4];
int win = 0;
for(int x = 0; x<4; x++)
master[x] = (int)(Math.random()*10);
System.out.println();
do {
int guess[] = new int[4];
int countMaster[] = new int[4];
String numguess = JOptionPane.showInputDialog("Enter your guess (4 digits, please)");
for (int x = 0;x<4;x++)
guess[x] = (numguess.charAt(x)-48);
int correctlyPlaced = 0;
int correct = 0;
for (int x = 0;x<4;x++)
if(master[x] == guess[x])
correctlyPlaced += 1;
for (int x = 0; x<4;x++)
for (int y = 0; y<4;y++)
if((guess[x]==master[y]) && (countMaster[y]==0)) {
correct++;
countMaster[y]=1;
y=5;
System.out.print("Guess:\t\t\t");
for (int x = 0;x<4;x++) {
System.out.print(guess[x]);
System.out.println();
System.out.println("Correct:\t\t"+correct);
System.out.println("Correctly Placed:\t"+correctlyPlaced);
if (correctlyPlaced==4) {
win=1;
} while(win<1);
System.out.println("You win!");
System.exit(0);
And here is the example code that my teacher gave me for how to draw a string on a JFrame:
Code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Fonts extends JFrame {
public Fonts()
super("Using Fonts");
setSize(420,125);
show();
public void paint(Graphics g)
super.paint(g);
g.setFont(new Font("Serif", Font.BOLD, 12));
g.drawString("Serif 12 point bold.",20,50);
public static void main(String args[])
Fonts application = new Fonts();
application.setDefaultCloseOperation (
JFrame.EXIT_ON_CLOSE);
I would like to be able to put "Guess," "Correct," and "Correctly Placed," on a JFrame, with their respective variables. Any ideas? Thank you!!!

And DrClap, I get that, but I'm not sure how to put my existing code into the class file that uses the JFrame.You wouldn't put your existing code in there. Your existing code is designed to run as a console app and most of it is concerned with the machinery of getting input from the user. If you want to write it as a Swing app, then you wouldn't need any code which writes to a JFrame in the first place.
So if your goal for learning on your own is to write GUI applications instead of console applications, then go off and read the Swing tutorials. Right now you're going down the wrong road. However if you're trying to learn something else on your own (I can't tell what that might be) then explain what it is you're trying to learn.

Need help with drawing shape and scrollbar
Hi everybody, I am newbie at java just started learning it. I have a few questions to ask.
1. Can anyone show me to how to draw a equilateral penatgon, octagon, ( 5-10 sized shape) with polar cordinate.
2. How to make the scrollbar back to their default state( work alone not together) after you use the "scrollbar1.setModel(scrollbar2.getModel())" method. For example I only want the scrollbar to work together when I choose circle as a shape after that I want the scrollbar to be back to normal when I pick another shape rectangle for example. When the scrollbar work together, how do I the make it so that the scrollbar move from bottom to top for vertical bar and from left to right for the horizontal bar when they work together instead of the default bar move from left(0) to right(max) for horizontal bar and from top(0) to bottom(max) for the vertical bar.Here's some code that builds regular polygonal icons.

Java Graphics -- Drawing Strings on JFrame
Hello and thank you. I'm relatively young and I apologize for asking noob questions. The problem I am having is that I realized after 3 hours of research and then writing this code that when multiple JPanels are added to a JFrame, they overlap (I think) over each other. As a result, the output of this program below is at the bottom right of the frame, the number 841 appears (the last number in my array) and everything else is blank.
And I could not at all understand how to create graphics objects. It kept giving me an error of not being able to be instantiated. And to be honest, I don't even really understand whats going on when I add the text to my JPanel. I never call paintComponents. And definately I could never even make a graphics object to provide it the parameter required. Anyway, I resolved to use Jpanels because they can be removed using the remove function of the JFrame. And It is vitally important that I can delete the strings off my frame. Here is my code:
package main;
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class VisualFrame extends JFrame{
ArrayList<JPanel> numbers = new ArrayList<JPanel>();
public VisualFrame(){
setSize(1000, 500);
setTitle("Binary Search");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
public void createPanels(int[] array){
int x = 10;
int y = 20;
int xOffset = 50;
int yOffset = 50;
for(int i=0; i<array.length; i++){
String num = Integer.toString(array);
numPanel panel = new numPanel(num, x, y);
numbers.add(panel);
add(panel);
x = x+xOffset;
if(x>this.getWidth()){
x = 10;
y = y+yOffset;
class numPanel extends JPanel{
String num;
int x;
int y;
public numPanel(String str, int x, int y){
num = str;
this.x = x;
this.y = y;
public void paintComponent(Graphics g){
g.setColor(Color.black);
g.setFont(new Font("Times", Font.BOLD, 12));
g.drawString(num, x, y);
My main method is inside of a different class:
public static void main(String[] args){
VisualFrame frame = new VisualFrame();
frame.createPanels(array);
}Firstly, do I even have the problem I'm having right? If so,
Is there a way to restrict the size of the panels to the length and width of what it contains?
Or can someone give me a good, very detailed link to how to use Graphics? Or perhaps someone could prove to me a good method.

Help with comparing string array with parameters
I've posted my code in full so hopefully everyone can see exactly what I have been doing.
Note - my code uses the observer/observable model. The method I am having the problem with the if statement is in the class HSBC.
Basically when the pin count reaches 4 (in the atm class) it sends the userid & pincode) over to the checkPinAndUserId(String pinCode, String userCode) method. Here the if statement should check the userid to see if the string parameter matches a string in the array. If it does it should check in the same position in the pin array to check the pin no is correct and then return true.

[\code]I wasn't trying to annoy anyone at all.
I'm new to java and have been told that using the observer/observable model is not considered basic java. So that is the only reason I posted it in this section. At the same time i feel that the bit I'm struggling with is actually basic - hence posting it in the basic section. I'm not sure if people of all abilities check all forums or just the ones they feel at at their standard.
So appologies if you've taken offence. -
im in the process of making a network whiteboard as a project for college and i was wondering if anyone could help me with a problem im having. When my application minimises or a window is placed over the application the drawing is erased, even if a window is placed over a certain part of the application it erases the part it covers is there any way to stop this from happening i cant seem to fix it, any help is appreciated, thanks
You should be buffering what the whiteboard is to draw, either as a BufferedImage or in some
data structure so that you can refresh when asked to repaint. Are you doing that, or are you
just drawing new graphics as it arrives from the server? -
Still Need Help with this String Problem
basically, i need to create a program where I input 5 words and then the program outputs the number of unique words and the words themselves. for example, if i input the word hello 5 times, then the output is 1 unique word and the word "hello". i have been agonizing over this dumb problem for days, i know how to do it using hashmap, but this is an introductory course and we cannot use more complex java functions, does ANYONE know how to do this just using arrays, strings, for loops, if clauses, etc. really basic java stuff. i want the code to be able to do what the following program does:
import java.io.*; import java.util.ArrayList;
public class MoreUnique {
public static void main(String[] args) throws IOException{ BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String str[] = new String[5]; int uniqueEntries = 0; ArrayList<String> ue = new ArrayList<String>();
for (int i = 0; i < 5; i++) { System.out.print((i +1) + ": "); str[i] = br.readLine(); }
for (int j = 0; j < 5; j++) {
if (!ue.contains(str[j].toLowerCase())) { ue.add(str[j].toLowerCase()); } } uniqueEntries = ue.size(); System.out.print("Number of unique entries: " + uniqueEntries + " { ");
for (int q = 0; q < ue.size(); q++ ) { System.out.print(ue.get(q) + " "); } System.out.println("}"); } } but i need to find how to do it so all 5 words are put in at once on one line, and without all the advanced java functions that are in here, can anyone help out?you have to compare string 0 to strings 1-4, then
string 1 with strings 2-4, then string 2 with strings
3 and 4 then string 3 with string 4....right???Here's a way to do it:
public class MoreUnique {
public static void main(String[] args) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
final int NUM_WORDS = 5;
String[] words = new String[NUM_WORDS];
int uniqueEntries = 0;
for(int i = 0; i < NUM_WORDS; i++) {
System.out.print((i+1)+": ");
String temp = br.readLine();
if(!contains(temp, words)) {
words[uniqueEntries++] = temp;
System.out.print("Number of unique entries: "+uniqueEntries+" { ");
for (int i = 0; i < uniqueEntries; i++ ) {
System.out.print(words[i]+" ");
System.out.println("}");
private static boolean contains(String word, String[] array) {
Your code here: just a simple for-statement to
loop through your array and to see if 'word'
is in your 'array'.
}Try to fill in the blanks.
Good luck. -
I just upgraded to CP 5. Need help with drawing objects.
I am trying to put a simple drawing object around a word. Like a square. I can't figure out how to not have any fill, just the outline of the box. Any suggestions? I was able to do this in CP 4.
Hi there
Personally, I'd use a Highlight Box to accomplish this. But that's just me.
Here are the steps for a square drawing object. I'll assume you have already inserted the object and placed it and all you want are instructions for dealing with the fill.
Look inside the properties inspector at the Fill & Stroke section. Click the Fill color and configure Alpha to 0%.
Cheers... Rick

Need some help with the String method
Hello,
I have been running a program for months now that I wrote that splits strings and evaluates the resulting split. I have a field only object (OrderDetail) that the values in the resulting array of strings from the split holds.Today, I was getting an array out of bounds exception on a split. I have not changed the code and from I can tell the structure of the message has not changed. The string is comma delimited. When I count the commas there are 26, which is expected, however, the split is not coming up with the same number.
Here is the code I used and the counter I created to count the commas:
public OrderDetail stringParse(String ord)
OrderDetail returnOD = new OrderDetail();
int commas = 0;
for( int i=0; i < ord.length(); i++ )
if(ord.charAt(i) == ',')
commas++;
String[] ordSplit = ord.split(",");
System.out.println("delims: " + ordSplit.length + " commas: " + commas + " "+ ordSplit[0] + " " + ordSplit[1] + " " + ordSplit[2] + " " + ordSplit[5]);
The rest of the method just assigns values to fields OrderDetail returnOD.
Here is the offending string (XXX's replace characters to hide private info)
1096200000000242505,1079300000007578558,,,2013.10.01T23:58:49.515,,USD/JPY,Maker,XXX.XX,XXX.XXXXX,XXXXXXXXXXXXXXXX,USD,Sell,FillOrKill,400000.00,Request,,,97.7190000,,,,,1096200000000242505,,,
For this particular string, ordSplit.length = 24 and commas = 26.
Any help is appreciated. Thank you.Today, I was getting an array out of bounds exception on a split
I don't see how that could happen with the 'split' method since it creates its own array.
For this particular string, ordSplit.length = 24 and commas = 26.
PERFECT! That is exactly what it should be!
Look closely at the end of the sample string you posted and you will see that it has trailing empty strings at the end: '1096200000000242505,,,'
Then if you read the Javadocs for the 'split' method you will find that those will NOT be included in the resulting array:
http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#split(java.lang.String)
split
public String[] split(String regex)
Splits this string around matches of the given regular expression. This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
Just a hunch but your 'out of bounds exception' is likely due to your code assuming that there will be 26 entries in the array and there are really only 24. -
Need help with attributed string in NSMenuItem
I'm trying to implement a contextual menu for a view in one of my applications. I want it to be dynamic, based on where you click in the view. It works fine if I don't try to mess with the font size of the menu. If I try to make the menu font smaller, the menu will appear blank, and its action won't get triggered, but only if there's only one menu item. If there are two or more, they'll all show up.
I've done a bunch of searching, and found some code examples where they put in a dummy item, then remove it later, but so far, that hasn't helped me, either. I've posted an example project (~44KB) on my web site that illustrates this, if you'd like to see it in action (the example doesn't include the "dummy fix", by the way, but it's easy enough to add).
Here's the code where I customize the menu:
<pre class="command">-(NSMenu *)menuForEvent:(NSEvent *)theEvent
NSPoint mouseLoc = [self convertPoint:[theEvent locationInWindow] fromView:nil];
NSLog(@"Raw Mouse Location: %2.1f, %2.1f", mouseLoc.x, mouseLoc.y);
// Get my blank menu:
NSMenu *tzMenu = [self defaultMenu];
// Set up my string attributes:
NSMutableDictionary *menuAttributes = [[NSMutableDictionary alloc] init];
[menuAttributes setObject:[NSFont fontWithName:@"Lucida Grande" size:11] forKey:NSFontAttributeName];
if (mouseLoc.x < 220) // Make just one menu item.
int i;
for (i=0; i<1; i++)
[tzMenu addItemWithTitle:@"Item" action:@selector(changeMapDot:) keyEquivalent:@""];
NSMenuItem *lastItem = [tzMenu itemAtIndex:[tzMenu numberOfItems] - 1];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:@"Item" attributes:menuAttributes];
// Comment out this next line and the menu item appears in the default font:
[lastItem setAttributedTitle:attrString];
[attrString release];
else
int i;
for (i=0; i<3; i++) //Make three items. These always appear.
[tzMenu addItemWithTitle:@"Item" action:@selector(changeMapDot:) keyEquivalent:@""];
NSMenuItem *lastItem = [tzMenu itemAtIndex:[tzMenu numberOfItems] - 1];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:@"Item" attributes:menuAttributes];
[lastItem setAttributedTitle:attrString];
[attrString release];
[menuAttributes release];
return tzMenu;
}</pre>Any tips that anyone has would be most apprecitated.
I'm not unalterably opposed to the regular system menu font if there's no way around this (the menus are pretty short: usually less then a dozen items), but aesthetically it looks nicer with a smaller font.
charlieHi,
You can use SUBSTR and INSTR
This should work in Oracle 9:
WITH cntr AS
SELECT LEVEL AS n
FROM dual
CONNECT BY LEVEL <= 3
, got_pos AS
SELECT x.txt
, c.n
, INSTR (x.txt, '[', 1, c.n) AS l_pos
, INSTR (x.txt, ']', 1, c.n) AS r_pos
FROM table_x x
CROSS JOIN cntr c
SELECT txt
, n
, SUBSTR ( txt
, l_pos + 1
, r_pos - (l_pos + 1)
) AS sub_txt
FROM got_pos
ORDER BY txt
, n
;Sorry, I don't have an Oracle 9 database available now; I had to test this in Oracle 10.
jimmy437 wrote:
... I have tried the "REGEXP_SUBSTR" but my database version is 9i, and it is available only from 10g.That's true. Regular expressions are very useful, but they're not available in Oracle 9 (or earlier).
Oracle 9 does have an Oracle-supplied package, OWA_PATTERN, that provides some regular expression functionality:
http://docs.oracle.com/cd/B12037_01/appdev.101/b10802/w_patt.htm
I know that's the Oracle 10, documentation, but it exists in Oracle 9, too.
Oracle 9 is very old. You should consider upgrading. -
Hi there,
I have a file that I need to read in and process. Took a while for me to realise it was unicode ("text from my file" was printing out as "t e x t f r o m m y f i l e") - Anyway, got there in teh end using:-
InputStreamReader fis = InputStreamReader(new FilInputeStream(filename), "UTF16");
dataSource = new BufferedReader(isr);My problem now is that I'm splitting the line (which is a comma seperated list of numbers) and coverting to int's:-
String line = dataSource.readLine();
String[] items = line.split(",");
int[] values = new int[12];
for(int i = 1; i < items.length; i++)
values[i-1] = Integer.parseInt(items);
Values is what I expect, a list of numbers, but items[] is being set to 0. Is this something to do with unicode? Must admit, I've never given the charater encoding any though up until now.
Any help would be really appreciated.
Thank,
Steve
usingSorry, found it. It was actually a buffer issue. For the record, just because I'm printing output in the middle of the loop, doesn't mean the value exists to be printed by the time System.out.println gets to it (my code was creating an exception for an unrelated reason a few lines down)
Thanks for your responses.

Help with sending string using setRequestProperty to servlet
I have a string that is encrpyted so it uses some wierd characters. An
example of the integer representation of the characters for a string that is
not working is:
26,162,91,52,153,136,227,53,190,0
When I recieve it on the servlet end and go to use it the integer
representation of the characters is all messed up therefore I can't decrypt
it properly. The servlet recieved:
26,162,91,52, 63 , 63 ,227,53,190,0
Where did the 63's come form??????? That is a "?" character and was not
part of the original string. I think it has something to do with when the
characters are converted to bytes or something but I can't seem to figure
out a way to fix it so that I get the original characters...
Please, any help would be very much appreciated. Thanks.Hmmm....my last post doesn't appear to make a whole lot of sense. I've got to start getting to bed earlier.
I guess I was a little excited when I realized what URLEncoder and URLDecoder were doing (by looking at the source, of course) which involves a lot of char conversion on the individual portions of your String. These classes are for US-ASCII text and really don't handle non-printable characters very well.
The passing of the characters across the connection remains a problem, and (without looking at source code) I believe the same problem is at the root; there is a basic encoding of your String into a format that doesn't support characters that aren't in the code page, and the question marks are substituted.
I haven't tried, but can suggest, using the encode/decode methods in the javax.mail.internet.MimeUtility class. This class comes with the J2EE download, but I'm afraid it may have some of the same shortcomings when it comes to characters it doesn't like (its methods appear to be mostly for mail HEADERS.)
You basically need either a UUEncode or Base64 encoder/decoder to translate your String into plaintext before it gets sent to the Servlet. The Java Commerce API (Java Wallet) contains a Base64Encoder/Base64Decoder but it is not licensed for reuse.
There might be other options (I don't know the full scope of your setup), but if all else fails, I can post a UUEncode class that will convert your encrypted string into plaintext for transmission. -

return reverse(s1);
public static void main (String [] args) {
stringrev str = new stringrev ();
String reverse = str.reverse ("jinux 2000");
System.out.println("Reversed String " +" " + reversed );
}haven't tested it, but the idea should be ok:
public String reverseString(String s)
String t = "";
for(int i=s.length()-1;i>=0;i--)
t += s.substring(i,i+1);
return t;
